If you look at the screen shot, you'll see what the user gets when they click on the "14" to the right of the month of July as it's listed on the right hand side.
When you click on Florida, all of the states represented on the calendar are hidden except for Florida using this script:
If I wanted to change that functionality so my user could click on Florida and then click on another state, rather than all of the states disappearing save the one that was just selected, I need to make it where they would see what they clicked on AS WELL AS the one they had chosen previously. I'll need a reset button as well, but the bottom line is I need to create a script that has the ability to each state one layer at a time without eliminating the one(s) that had been chose previously.
